Indeed. There is no point using w-m-c-p-l when we actually need the full
window size with fringes.

There is at least one workaround in org-agenda trying to account for the
face width. w-m-c-p-l should do better than that.

Attaching the patch.

Best,
Ihor

Subject: [PATCH] org-agenda: Use `window-max-chars-per-line' instead of
 `window-width'

* lisp/org-agenda.el (org-agenda-prepare):
(org-todo-list):
(org-agenda-show-new-time): Calculate the maximum number of chars
fitting into window via `window-max-chars-per-line' instead of
`window-with'.  The latter can return larger number when fringes are
disabled [1].
